1989 Volvo 780
As an enhancement to the three-point seat belt system, your Volvo 780 is equipped with a Supplemental
Restraint System (SRS). The Volvo SRS consists of a driver's side airbag with a driver's side knee
bolster. The system is designed to supplement the protection provided by the three-point seat belt system.
The interior of an SRS-equipped Volvo looks very much the same as any other. The only indications of
the system's presence are the "SRS" embossed on the steering wheel pad, and the knee bolster beneath
the steering column.
The airbag is folded and located in the center of the steering wheel. It is released only during a frontal or
front-angular collision in which the forces sustained by the car are equivalent to an impact into an
immovable barrier at a speed of approximately 12 mph (19 kph) or greater.
WARNING!
As its name implies, SRS is designed to be a SUPPLEMENT to - not a replacement for - the three-
point belt system. The airbag is not designed to be released in the event of a side or rear-end collision,
or during a rollover situation. For maximum protection, wear seat belts at all times.
The airbag system includes a gas generator(1), surrounded by the airbag itself(2). In the event of a
frontal or front-angular collision equivalent to impacting a rigid barrier at 12 mph (19 kph) or greater,
the sensor(3) activates the gas generator causing the airbag to be inflated with harmless nitrogen gas. As
the movement of the driver compresses the airbag some of the gas is expelled at a controlled rate to
provide better cushioning.
The entire process, including inflation and deflation of the airbag, takes approximately two-tenths of a
